Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application is a continuation of U.S. patent application Ser. No. 10/695,393, filed Oct. 29, 2003, which claims the priority of Korean Patent Application No. 2002-67968 filed Nov. 4, 2002, in the Korean Intellectual Property Officer the disclosure of which is incorporated herein in its entirety by reference.
    • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to an optical disc, and more particularly, to an optical disc having at least one recording layer, and apparatuses and methods for recording and reproducing data on the same.
  • 2. Description of the Related Art
  • Compact discs (CDs) and digital versatile discs (DVDs) are the most popular types of data storage media. In general, user data is recorded on pits of a recording layer of a read-only optical disc and recorded by changing a phase of a phase change material (PCM) on the recording layer of a rewritable optical disc which is covered with the PCM.
  • A pickup, which is included in an optical disc reproducing apparatus, detects a precise position of a track in which the user data is recorded, receives a laser beam reflected from the track, and reads the user data from the laser beam. A signal that the pickup uses to detect a position of a desired track is called a tracking signal. The tracking signal is obtained when a photo diode, which has a plurality of light receiving parts, receives the laser beam. Signals are generated from lights received by the respective light receiving parts, and then, the signals are added together or subtracted from each other. The tracking signal curves like an S-shape and right and left sides of the tracking signal, which are divided with respect to a central point of the tracking signal, have opposite polarities.
  • The polarities of the tracking signal change according to a type of the optical disc or physical characteristics of the recording layer on the optical disc, such as the physical characteristics of the pit or the track. In other words, the polarities of the tracking signal change from (−) to (+) and from (+) to (−) according to the type of optical disc or the physical characteristics of the recording layer. Therefore, when the optical disc is loaded into a conventional optical disc reproducing apparatus, the apparatus determines the polarity of a tracking signal by trial and error, detects the position of the track in which the user data is recorded based on the polarity, and reads the user data from the track. That is, the conventional optical disc reproducing apparatus spends considerable time in detecting the polarity of the tracking signal before reading the user data, thereby delaying a reproduction of the user data.
  • Meanwhile, a reflectivity of the optical disc is a ratio of a power of the laser beam reflected from the recording layer of the optical disc to the power of the laser beam incident on the recording layer. The reflectivity also depends on the type of optical disc or the physical characteristics of the recording layer, and therefore, the conventional optical disc reproducing apparatus detects the reflectivity by trial and error.

    • DETAILED DESCRIPTION OF THE EMBODIMENTS
  • Reference will now be made in detail to the present aspects of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The aspects are described below in order to explain the present invention by referring to the figures.
  • FIG. 1 is a schematic block diagram of an optical disc recording apparatus, according to an aspect of the present invention. Referring to FIG. 1, the recording apparatus includes a recording unit 1 and a controller 2 to record information regarding a polarity of a tracking signal and/or a reflectivity of an optical disc 100 on a burst cutting area (BCA) on the optical disc 100. The controller 2 creates the information regarding the polarity of the tracking signal and/or the reflectivity of the BCA and the recording unit 1 records at least one of tracking polarity information and reflectivity information on the BCA. Thus, the BCA of the optical disc 100, according to an aspect of the present invention, includes the tracking polarity information and/or the reflectivity information.
  • FIG. 2 is a schematic block diagram of an optical disc reproducing apparatus, according to an aspect of the present invention. Referring to FIG. 2, the reproducing apparatus includes a reading unit 4 and a controller 5. The reading unit 4 reads the tracking polarity information and/or the reflectivity information from the BCA on the optical disc 100, according to an aspect of the present invention, and provides an analysis result indicative thereof to the controller 5. Then, the controller 5 analyzes the tracking polarity information and/or the reflectivity information and reproduces user data from the optical disc 100 based on the analysis result.
  • The recording apparatus of FIG. 1 is an apparatus used in a mastering process by a disc manufacturer. The reproducing apparatus of FIG. 2 is an apparatus to reproduce the tracking polarity information and/or the reflectivity information, not the user data, from the BCA. Thus, the reproducing apparatus of FIG. 2 can be included in both the optical disc recording apparatus and the optical disc reproducing apparatus because the reproduction of the above information can be carried out when recording or reproducing the user data on the optical disc 100.
  • FIG. 3 is a schematic block diagram of the optical disc 100, according to an aspect of the present invention. Referring to FIG. 3, a first recording layer l 0 is formed on the optical disc 100. The first recording layer l 0 includes a clamping area C, the BCA B, a lead-in area L1, and a lead-out area LO. The clamping area C is an area that is pressurized by a clamping tool in order to clamp the optical disc 100. In general, the clamping area C is circular band shaped and formed in an inner portion of the optical disc 100. The BCA B is an area in which the tracking polarity information and/or the reflectivity information is recorded. The particulars of the optical disc 100, such as a corresponding serial number and manufacturing date, may be further recorded in the BCA B. A data area in which the user data is recorded, is present between the lead-in area L1 and the lead-out area LO. If the first recording layer l 0 is formed of a phase change material (PCM), the tracking polarity information and/or the reflectivity information may be recorded with a pattern of crystalline and/or non-crystalline marks. A method of recording information in the BCA B is disclosed in Korean Patent Application No. 2001-47957 entitled “Optical Disc and Methods for Recording and Reproducing Essential Information of Optical Disc,” also filed by the present applicant.
  • FIGS. 4A and 4B are schematic block diagrams of the optical disc 100, according to another aspect of the present invention. Referring to FIGS. 4A and 4B, the first recording layers l 0 and a second recording layer l 1 are formed on the optical disc 100. Each of the first recording layer l 0 and the second recording layer l 1 includes the clamping area C, the lead-in area LI, and the lead-out area LO. The data area in which the user data is recorded is present between the lead-in area LI and the lead-out area LO. The clamping area C, the lead-in area LI, and the lead-out area LO are the same as those explained with respect to FIG. 3, and therefore, their descriptions will not be repeated here. Further, the BCA B is present between the clamping area C and the lead-in area LI of the first recording layer l 1. The tracking polarity information and/or the reflectivity information is recorded in the BCA B, according to an aspect of the present invention. The particulars of the optical disc 100, such as the corresponding serial number and the manufacturing date, may be further recorded in the BCA B. If the first recording layer l0 is formed of the phase change material (PCM), the tracking polarity information and/or the reflectivity information may be recorded with the pattern of the crystalline and/or the non-crystalline marks.
  • FIGS. 5A and 5B are schematic block diagrams of the optical disc 100, according to still another aspect of the present invention. Referring to FIGS. 5A and 5B, the first recording layer l 0 and the second recording layer l 1 are formed on the optical disc 100. Each of the first recording layer l 0 and the second recording layer l 1 includes a clamping area C, a lead-in area LI, and a lead-out area LO. The data area in which the user data is recorded is present between the lead-in area LI and the lead-out area LO. The clamping area C, the lead-in area LI, and the lead-out area LO are the same as those explained with respect to FIG. 3, and therefore, their descriptions will not be repeated here. According to an aspect of the present invention, the BCA B is formed on the second recording layer l 1, unlike in FIGS. 4A and 4B in which the BCA B is present on the first recording layer l 0. That is, the BCA B of FIGS. 5A and 5B is present between the clamping area C and the lead-in area LI of the second recording layer l 1. If the second recording layers l 1 is formed of the phase change material (PCM), the tracking polarity information or reflectivity information may be recorded with a pattern of crystalline and/or non-crystalline marks.
  • In conclusion, the optical disc 100 of FIGS. 5A and 5B is different from that of FIGS. 4A and 4B in that the BCA B is present in the second recording layer, not the first recording layer.
  • FIG. 6A illustrates a data structure of the BCA of the optical disc 100, according to an aspect of the present invention. Referring to FIG. 6A, the tracking polarity information is recorded in the BCA, according to an aspect of the present invention. The tracking polarity information provides the polarity of the tracking signal related to the optical disc 100. The tracking signal curves like an S-shape and corresponding right and left sides, which are divided with respect to the central point of the tracking signal, have opposite polarities. The polarity of the tracking signal changes according to a type of the optical disc 100, or physical characteristics of the recording layer such as the physical characteristics of a pit or a track. In other words, the polarities of the tracking signal change from (−) to (+) and (+) to (−) according to the type of the optical disc 100 or the physical characteristics of the recording layer. The particulars of the optical disc 100 may be further recorded in the BCA, as well as the tracking polarity information.
  • FIG. 6B illustrates a data structure of the BCA of the optical disc 100,1 according to another aspect of the present invention. The tracking polarity information and/or the reflectivity information is recorded in the BCA, according to an aspect the present invention. Here, the tracking polarity information is as described with reference to FIG. 6A. The reflectivity information provides the reflectivity of the optical disc 100, which is a ratio of the power of a laser beam reflected from the recording layer of the optical disc 100 to the power of the laser beam incident on the recording layer. The reflectivity also changes according to the type of the optical disc 100 or the physical characteristics of the recording layer.
  • Meanwhile, the tracking polarity information is recorded in both the BCAs of FIGS. 6A and 6B, but only the reflectivity information can be recorded if needed.
  • FIG. 7 illustrates a data structure of the information recorded in the BCA of the optical disc 100, according to an aspect of the present invention. In detail, FIG. 7 shows an example of the BCA in the optical disc 100 having two recording layers as shown in FIGS. 4 and 5. The tracking polarity information is repeatedly recorded four times in the BCA and the recording begins at leading bytes of the BCA. First two bits b1b0 of the tracking polarity information are identifiers of the respective information that is repeatedly recorded. If the first two bits b1b0 are 00, the information indicates that first tracking polarity information is recorded in the BCA. If the first two bits b1b0 are 01, the information indicates that second tracking polarity information is recorded in the BCA. If the first two bits b1b0 are 10, the information indicates that third tracking polarity information is recorded in the BCA. If the first two bits b1b0 are 11, the information indicates that fourth tracking polarity information is recorded in the BCA. Repetitive recording of the information increases a robustness of the information. Even if an error occurs in one of the repeated recordings, it is possible to read desired information from the other recordings. The other six bits b7b6b5b4b3b2 provide the information. The bit b2 includes flag information indicating whether or not other information, i.e., the particulars of the optical disc 100, is recorded in the BCM. If the bit b2 is 0, the information indicates that the other information is not recorded in the BCM. If the bit b2 is 1, the information indicates that the other information is recorded in the BCM. The bits b7b6b5b4b3 represent the tracking polarity information and can be defined as follows:
      • 00000: first recording layer=type A, second recording layer=type B
      • 00001: first recording layer=type B, second recording layer=type A
      • 00010: first recording layer=second recording layer=type A
      • 00011: first recording layer=second recording layer=type B
  • For instance, when the other information is not recorded in the BCA, and the polarities of the tracking signals related to the first and second recording layers are type B and type A, respectively, the six bits b7b6b5b4b3b2 is expressed as ‘000010’. When the other information, such as the particulars of the optical disc 100, is recorded in the BCA and both polarities of the tracking signals related to the first and second recording layers are type A, the six bits b7b6b5b4b3b2 is expressed as ‘000101’.
  • If 1 byte is not enough to express the tracking polarity information, for example, if the number of recording layers is more than 2, it is possible to express the tracking polarity information using additional bits in addition to the 1 byte.
  • When the optical disc 100 is loaded into a disc drive of the optical disc reproducing apparatus, the disc drive easily accesses leading bytes of the BCA so as to read the tracking polarity information and/or the reflectivity information. Accordingly, the recording of the tracking polarity information and/or reflectivity information may begin on the leading bytes of the BCA.
  • A method of reproducing the data from the optical disc 100, according to an aspect of the present invention, will now be described. As mentioned above, the data that is reproduced using the method is not the user data, but the tracking polarity information and/or the reflectivity information recorded in a BCA of the optical disc 100. The reproduction of such data can be performed both when recording and reproducing the user data in a data area.
  • FIG. 8 is a flowchart illustrating the method of reproducing the data from the optical disc 1 00, according to an aspect of the present invention. Referring to FIG. 8, at operation 801, when the optical disc 100 is loaded into the disc drive of the reproducing apparatus of FIG. 2, at operation 802 the optical pickup included in the disc drive reads the tracking polarity information from the BCA of the optical disc 100. At operation 803, the reproducing apparatus (or the disc drive) performs the tracking on the optical disc 100 using the read tracking polarity information without trial and error, and records or reproduces the user data in a data area of the optical disc 100. In other words, the optical pickup provides the tracking polarity information to the disc drive, and then, the disc drive controls the optical pickup using the information to perform the recording or the reproducing of the user data on the optical disc 100.
  • FIG. 9 is a flowchart illustrating the method of reproducing the data from the optical disc 100, according to another aspect of the present invention. Referring FIG. 9, at operation 901, when the optical disc 100 is loaded into the disc drive of the reproducing apparatus of FIG. 2, at operation 902, the optical pickup included in the disc drive reads reflectivity information from the BCA of the optical disc 100. At operation 903, the reproducing apparatus (or the disc drive) adjusts the write/read power of the laser beam using the read reflectivity information without trial and error, and records or reproduces the user data in the data area of the optical disc 100. In other words, the optical pickup provides the reflectivity information to the disc drive, and then, the disc drive controls the optical pickup using the information to perform the recording or the reproducing of the user data on the optical disc 100.
  • As described above, tracking polarity information and/or reflectivity information is recorded in a BCA of an optical disc according to an aspect of the present invention. Accordingly, it is possible to obtain the tracking polarity information and/or reflectivity information without trial and error and directly record or reproduce user data in a data area of the optical disc.
  • Although a few aspects of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this aspect without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
